1 Underpinning Readiness at the Right Cost and Effective Life Cycle Maintenance Distribution Statement A "Approved for public release; distribution is unlimited" Presented to: DoD Maintenance Symposium Presented by: 14 November 2011 RDML(select) CJ Jaynes, USN Assistant Commander for Logistics & Industrial Operations, Naval Air Systems Command

2 Condition Based Maintenance (CBM) Objectives Reduce Total Ownership Costs Increase Operational Availability Improve Flight Safety Improve Maintenance Efficiency 2

3 CBM Definition Condition Based Maintenance System of on-board sensors, self-monitoring systems, and off-board diagnostics that enable problem detection and maintenance only when needed CBM Elements On-Board Sensors/Self-monitoring Systems Ground Stations Data Management & Engineering Analysis Outcomes Mechanical Diagnostics Component condition / health Structural Appraisal of Fatigue Effects (SAFE) accurate usage data / component life Fatigue Life Expended Tired Unexpected failures Assumed Life Light Use Early Removals Flight Hours 3

4 CBM Working Group & Demo Project NAVAIR CBM Working Group formed to provide Enterprise-wide CBM solutions and policy Focused on Demo Project with an H-53E squadron to set up an end-to-end CBM construct Identify gaps Evaluate CBM tools Develop data architecture and warehousing requirements Develop gov t owned data analysis tools and processes Establish CBM Enterprise policy Track 7 life limited and 5 health monitored components 4
